SHUTTLE-MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 415,879, dated November 26, 1889.

Application iilecl March 18, 1889. Serial No. 303,658. (No model.)

To all whom, t may concern:

Be it known that we, THOMAS MURPHY and JOHN IV. BROADHEAD, both of Rrovidence, in the county of Providence and State of Rhode Island, have jointly invented certain new and useful Improvements in Shuttle- Motions for Looms, of which the following is a full, clear, and exact description, reference being 'had to the accompanying drawings, forming part of this specification.

The object of our invention is to provide a device which will support the sweepsticlt and strap and allow of the same being readily adjusted, so as to exert more or less powei` through the picker-stick.

To t-he above purposes our invention consists in the combination of the different parts of the device, as will be more fully set forth hereinafter.

In the accompanying' drawings, Figure 1 represents a side view of our improved device in operative position. Fig. 2 is a perpendicular sectional View showing the sweep-stick and part of the sweepstrap and pad in section and a portion of the'picker-stick. Fig. 3 is a sectional view taken on the line 3 3 of Fig. l. Fig. 4 is a sectional View taken on the line Jr et of Fig. 1, and Fig. 5 is a perpendicular sectional view showing another Vform of sweep-strap.

In the drawings similar numbers of reference designate eorrespondin g parts throughout. Y

Referring to the drawings, G indicates an arm, which is supported on the lay-shaft 7; 8, the picher-stick, which is mounted on the arm 6.

9 is the sweep-stick, and 10 the sweep-strap.

11 is a light rod, )referably made of metal.

12 designates an adjustable slide secured on the arm 0 and having the slot 13 and boss 11. The bolt 15'is provided with the shoulder 1C and extension 17, upon which the picker'stick 8 is pivoted and held in place by the pin 18. The bolt 19, passing through the sweep-strap and sweep-stick, is provided with a shoulder 20 and an extension 21.

The object of the slot 13, formed in the slide 12, is to allow of the slide being moved on the bolt 15 to lift or lower the sweep-strap and sweep-stick through the rodll, and, as it is desirable that the rod 11 should maintain a position parallel to the picker-stick, the end of the slide carrying the boss 14: would necessarily be lifted or lowered as well as moved toward or away from the bolt 15, whereby the slide 12 would assume a diagonal position. The bolt 15 is passed through the slot 18 in the slide 12, then through a hole inthe arm 6,when the nut 22 is screwed up, so as to securely hold the slide in the desired position and yet allow of a free movement of the pickerstick 8 upon the extension 17. The rod 11 is pivoted at one end on the eX- tension 21 and at the other end on the boss 14, on both of which it is held by the pins 23 and 24, respectively, so as to freely move with the picker-stick. It will bereadily seen that by loosening the nut 22 the slide can be adjusted so that the rod ll may be lifted or lowered, and with it the sweep-stick and sweep-strap, and at the same time the lower end of the rod 11, supported on the boss 14, may be moved in or out from the middle line of the picker-stick to correspond to the position of the upper end, supported on the extension 21, after which, the nut being screwed up, the bolt 15 will securely hold the slide in the desired position, and the rod, being pivoted on the boss 14, will maintain a position parallel with the piclterstick- By reason of supporting the sweep-stick by the rod 11 we are enabled to use a metallic use a pad 25, which is formed with angular faces, so as to give a better bearing on the picker-stick.

In Fig. 5 we have shown the strap lO as formed with angular faces, a flat strap being used for the pad, but producing the same result as that shown in Fig. 2.

All the parts are simple and durable in construction and allow of the ready adjust ment of the sweep-strap on the picker-stick, so that lnore or less force may be brought to bear by the same on the shuttle.

Ilaving thus described our invention, we claim as new and desire to secure by Letters Patente- A 1. The coinbination,with a picker-stick, the sweep-stick, and sweep-strap of a loom, of a supporting-rod pivotally secured to an ad- 4sweep-strap, if preferred, in which ease we IOO justable slide and t-o the sweep-stick and the adjustable slide adjustably secured by the fulcrnm-pin of I[he picker-stick, substantially as herein shown and described.

2. The combination of the sweep-strep provided with a pad, the sweep-stick, the supporting-rod, the adjustable slide, and the picker-stick, substantially as herein shown und described.

3. Tlie combination of the picker-stick 8, adjustable slide 12, rod 11, the sweep-stick 9, and sweep-strap 10, substantially as herein shown and described.

f1. The combination of the pickerstick 8, adjustable slide 12, provided with the slot 13 and boss 14, Jche bolt 15, provided with the collar 16, the nut- 22, the sweep-stick 9, the sweep-strap 10, and the rod 11, mounted on the boss 14, for supporting the sweep-strap 10 `@und sweep-stick, substantially as herein shown and described.

5. The combination of ille picker-stick 8, adjustable slide 12, provided with the boss 14, the bolt 19, and the rod 11,tl1e sweepstick 9, and sweep-strap 10, provided with the pad 25, substantially as herein 'shown and described.
